Miu Sakurai, age 15, attends a Catholic school where she prays every day for her admired Shion Amamiya to return her love. When that doesn't work, she places her faith in a book of magic and tries casting one of its spells. However, it's not love that manifests... it's Satan! "The recompense for the contract to grant your wish is your virginity," he tells her, and this is Miu's virgin crisis!

Volume 4: Satanic Honey and Satanic Cohabitation

From JShoujo:
It’s a story about a girl who lost her every memory. One stormy night a sudden meeting changes her life forever. She starts anew while still trying to set the pieces of the puzzle that was once her life. Soon after, a love that puts everything on a line is born in the girl’s heart.

Himeno's chest will hurt if any boy touches her because she has the diamond of the heart. However, when she was young, she befriended two boys -- the gentle Mamoru and the blunt Keigo -- who are able to touch her without harming her. Without knowing about the diamond of the heart, both Mamoru and Keigo promised to protect Himeno. When some people threaten to take Himeno's heart, who else will protect her but her knights?
